I don't understand why you need an idler arm, but I would use a belcrank from a Control line plane like these:

control line horns appear to operate the pushrod at right angles to the pull-pull wires, i need to have the pushrod in the same direction as the pull-pull.
i could simply add another hole to the control line horn to do the job. QED.

many thanks
